Table of Contents
The aim of DIGAR’s collection of Estonian articles is to provide a unite web portal for all digitally created or digitised newspapers, journals and other serials that are published abroad in Estonian or here in Estonia and make them accessible.
You can just browse the collection or search articles by content, read the full texts, make notes, compile a bibliographic index, and send the lists to your e-mail account, share information through social networks and a lot more.
Everything published in these publications has been treated as articles – except photos and illustrations, advertisements, comics, horoscopes, crosswords and Sudoku puzzles.
All text is inserted automatically using optical character recognition software. The text has not been edited, except the names of authors, article headlines and photo captions.
Insert one or more keywords to the search field and click Search . The search includes by default the whole portal (full text), but you can choose to search only by article headline, author or tags. The result shows the entries that contain the keyword. For more complex searches you can use Detailed search.
Search is NOT case-sensitive. A search for ülle tamm is the same as a search for Ülle Tamm.
To search a certain phrase use quotation marks around it, e.g. "Kriitilise lingua franca ajastu".
NB! If you don’t use quotation marks, words are treated as keywords irrespective of their order.
For example, to search the phrase Kriitilise lingua franca ajastu from full text you have to insert it like this:
Logical Operators AND, OR, NOT
You can narrow down results by using logical operators:
AND – Result contains all keywords; limited search
OR – Result contains at least one of the keywords; expanded search
NOT – Result does not contain the keyword; limited search
NB! Logical operators have to be inserted always in uppercase (AND, OR, NOT), otherwise the system treats them as keywords.
For example, to search about both loodus and mets from full text, it has to be inserted like this:
Shortening the Keyword
To search only by the beginning of a word cut it off with an asterisk (*) that replaces the rest of the letters. For example, inserting a keyword rong*, the result shows all articles containing words like rongi, rongile, rongkäigus, rongijuhi, rongiaegadega, rongaema etc.
Detailed search enables you to narrow down and limit you search by several features and combine different search fields. The link Detailed search can be found on the right of the main search field.
Detailed search helps you limit the results by:
You can search from the whole portal (full text) or you can choose to search only by article headlines, author or tags.
The result is shown as a numerated list of found articles or pages. It contains bibliographic data, such as:
To narrow down the search results, use thematic clusters assembled according to many features, such as:
The features are sorted according to frequency. Not more than four of the first features are opened by default in the thematic cluster. The whole cluster opens when you click below it on the link More.... To inactivate some of the limiting features, click the icon x.
NB! The clusters values are case sensitive! E.g. if you are looking for an author in the form of Ülle Tamm, it will be presented in the thematic cluster also as ÜLLE TAMM. The system does not merge the different forms together, in the author’s thematic cluster they will be shown on separate rows.
Order of the Results
By default the results are ordered so the best matches are first. The results can also be reversed and/or ordered according to other features:
Browsing the Publications
For browsing you can use a calendar, the list of publications and the table of contents of a specific issue. The calendar is useful for searching articles by date. Clicking on a certain date opens a list of all publications published that day.
The list of publications (the tab PUBLICATIONS) opens an alphabetical list of all publications in the portal.
Clicking on publication categories opens a list of publications belonging to that certain category. There you can also choose to see the full list (link Show all publications).
Articles, pages, publication issues and publications have been provided with permalinks. For articles and pages, they are shown in the search results.
For publications, permalinks are shown in the publication’s information box.
Content Viewer’s Functions
Depending on copyright agreements and digitisation technology, the publication may open on three different levels: publication, page or article.
The content viewer is divided into two parts: the right side displays the publication’s picture and the left side displays the table of contents, the text, a link for editing and an option to add tags. Choosing an article by clicking on the table of contents, the article will be brought forward on the right and its automatically recognised text will appear on the left instead of the table of contents. Clicking on the right side (on the publication’s picture) on some other article, it will be brought forward and its automatically recognised text will appear on the left. The keywords are marked (only the exact match) in the article and also in the automatically recognised text.
You can browse the publication by dragging the picture on the right. Moving around the publication on the right, the parts where the cursor is on the moment are highlighted. The content viewer lets you move to the previous or next issue or search result. You can also zoom in and out. Publications and pages in PDF format that do not have access restrictions can be downloaded for printing.
The content viewer lets you print chosen articles – right-click on the article and choose Clip this article. The clipped article will be automatically aligned in one column and displayed according to the size of your own monitor, so the result might not be exactly the same as it was in the newspaper.
NB! If access restrictions have been applied to the publication, the content viewer displays only the lock icon and information about the restrictions (e.g. View access: in the National Library of Estonia and other libraries receiving legal deposit copies).
Advanced query syntax
Query terms can be boosted to increase their importance in the search, changing the order of the search results. This is done by adding "^" and a boost factor at the end of the term, e.g. hamilton river^2 will treat "river" as more important than "hamilton" when ranking the search results returned.
Wildcard searches can be performed by including "?" (single character wildcard) or "*" (multiple character wildcard) in the query term. For example, hamilt* will match all words starting with "hamilt".
Fuzzy searching can be done by adding "~1" at the end of individual terms, e.g. roam~1 will find terms like "foam" and "roams" as well as "roam". This can help to compensate for errors in the text due to the Optical Character Recognition process.
Proximity searching allows you to search for words that appear close together in the text. For example, "John Smith"~3 will find results containing both the words "John" and "Smith" where they are no more than 3 words apart. So as well as finding "John Smith" it will also find "John J. Smith", "John Frederick Smith", "John Fullerton-Smith", and even "Smith, John".
OCR – Optical Character Recognition
OCR (Optical Character Recognition) is an automatic text recognition process, during which documents are analysed with special software that identifies the parts containing text, pictures and tables.
OCR enables the opportunity for full text search. Still, you have to keep in mind that the result is never 100% accurate. The accuracy depends on many aspects: publication’s print quality, the quality of the microfilm that was scanned, design elements, the scanner and OCR software. Poor results may be caused also by low-quality paper, small print, different fonts, different layout of columns, and damaged pages.
To look at the OCR text, select the page/article and click the "Text of this page/Text of this article" link.
Editing the OCR Text
You can edit the automatically recognised text of the newspapers published before 1944. Corrections can be made only by users who have registered and logged in with their library username, ID-card or Mobile-ID.
To edit text, click on the left side of the viewer Correct this text. Choose a part you want to edit (e.g. an article). Now you can see the automatically recognised text on the left and you can edit it right there. The text can be edited row by row. The red box on the right helps you to follow the rows and see which text belongs to a certain row. When you have finished editing, click Save. NB! All saved changes will be immediately visible for all users. To quit, click Cancel, and all changes made since the last save will be cancelled.
You can continue editing by clicking Next on the following row or choosing another part on the right side of the viewer. To exit the editing mode, click Return to viewing mode. By clicking on the Save & exit, you can save and return to the viewing mode at the same time.
NB! Corrections have to be made exactly according to the way the text was published in the newspaper. You may not edit typographical errors or change punctuation marks and syntax or add your own comments and additions etc. Changes are being tracked by a moderator with the right to decline incorrect changes.

Adding Tags to Articles
Users can add their own tags to articles (link Add tag). A list of added tags is displayed in the tab TAGS. A thematic cluster is formed of the added tags; thereby helping you to limit your search. You can add or view added tags on the search result page and in the content viewer. Tags can be deleted only in the publication’s content viewer. To change a tag, delete the old one and add a new one.
Tags can be added only by users who have registered and logged in with their library username, ID-card or Mobile-ID.
You can see your added tags here: My account >> Recent activity >> Recently added tags.
NB! Tags have to be added according to the content of the article and following orthographic rules. Tagging is being tracked by a moderator with the right to edit incorrect tags and delete inappropriate or otherwise out of place tags.
Adding Articles to Private Lists
On the search result page, you can add articles to your own private list (link Add to private list). ). Lists can be formed only by logged in users.
Clicking on Add to private list you can form a new list or choose an existing one. While adding an article to a list, you can also add a note. You can form up to 10 lists and one list can contain up to 250 entries.
