POLAR is the Public Online Library Access and Retrieval system. It is an online catalog of materials available on ONU's campus and is maintained by both the Heterick Memorial Library and the Taggart Law Library.

- Patron borrowing through the OhioLINK central catalog
- Access to numerous citation and full-text databases

If you are performing a keyword search you can search by more than one term at a time by using the boolean operators AND, OR, or NOT.
- Horses AND cows located works dealing with both topics
- Horses OR cows locates works dealing with either topic
- Unions NOT trade eliminates works dealing with trade unions but would show works on credit unions.
- Authors should be entered last name first.
- No commas need be used between names, and the names need not be capitalized.
- Although you do not need to have an author's complete name, the more information that you give POLAR, the more precise will be the response. For example:
Smith ............................... Retrieves ................... 1426 authors
Smith Joan ....................... Retrieves ................... 3 authors
Smith Joan M ................... Retrieves ................... 1 author
To perform an author search, Rose Peter S. for example, enter the name in the search box and either click on the search button or press enter. You will see a list of the author's works.
From there you can click on individual publications to find out how to locate them.
POLAR allows you to perform truncated (shortened) searches. For example, you can search by an incomplete author name, book title, or subject. Just enter as much as you know. POLAR automatically truncates these searches.
To turn off the automatic truncation, use a vertical bar, |, at the end of a term. For example, a subject search under "cat" finds headings for:
Cat breeds, Cat Domestic, Cat Family, Catabaptists.
Searching under cat| limits you to just the term "cats."
When performing a keyword search, you can truncate the search by inserting an asterisk, *, at the end of a word.
For example, Computer* locates materials on:
Computer, Computerized, Computerization.
The title search will locate a work given all or part of the title, however the words that you provide must be in the correct order.
For example, to locate the work The Sun Also Rises enter:
The Sun Also Rises
Sun Also Rises
Words need not be capitalized.
If you are uncertain of the exact title, try a keyword search. Keyword searches are not affected by word order. Title searches are.
To perform a title search for I Sing the Body Electronic... enter the title in the search box and either click on the search button or press the Enter key.
POLAR provides lists of materials that faculty members have placed on reserve at either library. From the main POLAR screen, click on either "Course Reserves by Course name" or "Course Reserves by Name of Professor".
Enter as much of the professor's name or course name as you know. In the example, a professor's last name, Young, has been entered to view a list of his reserves.
Note that items for Heterick will be on reserve at the Circulation Desk. You will be told if the item is available or in use.
For more information about a work itself, you can click on its title.
In a subject search, the terms that you enter are compared to a pre-set list of authorized
subject headings. If you have provided an invalid subject heading you will either be given a cross reference to
an appropriate subject or told that your heading is not correct.
If you cannot think of a valid subject you should either:
Consult the 4-volume set of subject headings next to the Heterick Reference Desk or
Ask for help at the Reference Desk
To perform a subject search, enter your topic in the search box and either click on the search button or press the Enter key.
The sample search screen shows a subject search run for materials on microsoft corporation.
To obtain information about items that you either have in your posession or have requested, click on the "My Library Account" button on the POLAR main screen. You will see a verification screen where you will be asked for your name and barcode number.
Please Note - Your barcode number will be ID number as it appears on your ONU ID.
If you have items checked out, there will be a button "X Items currently checked out." Clicking on that button will show a screen with item titles, status (date due), and the call numbers.
In front of each item is a box which can be checked to renew an item or you can click on "Renew All" at the top of the screen.
Due Dates are noted in the Status box. It is an EXCELLENT idea to check this information to ensure that you do not have items coming due during a holiday break.
Any fines or unpaid fees will be noted at the top of the screen. For details, you can contact the Heterick circulation department at 2182.
Holds include items owned by ONU that are currently in use but which you have requested be kept for you upon their return and items that you have requested from other OhioLINK libraries.
Note that each item is preceded by a "Cancel" box. You can cancel holds on ONU-owned materials at any time.
You can cancel requests for OhioLINK items ONLY as long as another library has not shipped an item.
Searching When You are Uncertain of a Title
Keyword searches are not concerned with word order so they are useful if you know part of a work's title. For example, if you were looking for Policy Options for Stabilizing Global Climate: Draft Report to Congress, but you only remember that the title had the words global, climate, draft, and report, you could still search by entering the partial title.
Searching for Poems, Essays, Plays, Etc.
Many individual smaller works may not be cataloged under their own titles. Fortunately there is a place in each catalog record where this information may be entered, the contents note. If a contents note is available for your work the keyword search will look for it.
If, for example, you were looking for the text of William J. Bryan's speech, The Cross of Gold, you could do a keyword search under the title of the speech.
You would see a results screen with all matching works listed. The screen for the work containing the speech shows how the speech was located in the contents note.
Many, but by no means all, of the records in POLAR, have contents notes.
If an item is already in use, you can ask that it be held for you when it is returned.
You will know an item is in use when the "status" box in the catalog record for the item has a due date listed. When you see a due date, just click on the " Hold Item for Me " button to see the hold form.
Supply your name and barcode number along with any special instructions, e.g. a "not needed after" date.
Click on the "Submit Above Information" button at the bottom of the screen.
You will be called when the item is returned. It will be held at the Heterick Circulation Desk for 72 hours.
This arrangement is used for most materials at Heterick. It groups materials by subject. Enter as much of the
call number as you know.
Library of Congress Classification
The Taggart Law Library uses this scheme in its treatise (book) collection. Enter as much of the call number as you know.
POLAR provides a place for patrons to register suggestions or comments. At the POLAR main screen click on the "Comments/ Suggestions" button. You can enter up to six lines of text, though the individual lines are quite long.
When you have finished, click on the "Submit This Suggestion" button.
