Linking to Library Resources

Linking to items in the library catalog (Polaris) - Introduction

Direct or deep links can be made to single records or groups of records in Polaris. These links can be system-wide (i.e. covering Carroll Community College and Carroll Public Library as well as McDaniel), or, more commonly, limited to Hoover Library materials only.

Deep linking is useful in any number of circumstances, as it allows for custom result lists with no user input, as well as automatic limits to collections or locations, again without requiring user input. It also allows for research guides to link to the record for a specific title, so the user can check if it is in or out and get location information without having to go back to the catalog. For example, inserting the following code into the title box in a book widget (where the ISBN and the title are changed for each specific item) will create a direct link to this title in the PAC:

<A HREF="https://catalog.carr.org/search/searchresults.aspx?ctx=19.1033.0.0.4&type=Keyword&by=ISBN&term=9780123518309&limit=AB=19&query=&page=0">Functional neurobiology of aging</A>

The link can also be put into the URL box for the title (just this part:  https://catalog.carr.org/search/searchresults.aspx?ctx=19.1033.0.0.4&type=Keyword&by=ISBN&term=9780123518309) - either way will work.

A number of these links are already in use on the main catalog page:

The Faculty Publications List (using a Series limiter, &by=SE):

https://catalog.carr.org/search/searchresults.aspx?ctx=19.1033.0.0.4&type=Keyword&term=mcdaniel%20college%20faculty%20publication&by=SE&sort=RELEVANCE&limit=AB=19&query=&page=0

The DVD list (using a Bibliographic Record Set limiter, ?brs=):

https://catalog.carr.org/view.aspx?brs=73414&sort=TI

The types of deep links and their possible construction is detailed below. Note that for all of these, there may be multiple ways to construct a link that does the same thing using differing syntaxes.

Links to Individual Catalog Records

You can find a permalink for an individual item in the catalog from the full record of the item. When you find the item you want to link to, click on the title to bring up the full record. In the box to the right of the record, click on the email icon to bring up a new window.

Copy the URL from the bottom of the new window to paste into your application.

Types of Deep Links

There are a number of types of deep links that can be created:

Boolean deep links are also possible - a guide to boolean searching in Polaris is here: https://www.clan.lib.nv.us/polaris/help/content/1033/boolean.htm 

Boolean links are often necessary to limit retrieval to only Hoover Library titles (if that is desired). For each type of search, at least one Boolean example is given (as indicated by the &type=Boolean in the URL). Others can be constructed as deeply nested as logic will permit - some experimentation will likely be necessary for complex sets.

NOTE that some encoding of permalinks with spaces may fail if the space character is not converted to its ASCII equivalent. More information on this encoding can be found here: http://www.blooberry.com/indexdot/html/topics/urlencoding.htm This is most likely to occur in title and subject searches with multiple terms separated by spaces.

Link by Control Number (MARC 001)

https://catalog.carr.org/view.aspx?ctx=19.1033.0.0.4&cn={control_number},{control_number}, …

Single Control Number:

https://catalog.carr.org/view.aspx?ctx=19.1033.0.0.4&cn=9999

Separate multiple Control Numbers with a comma:

https://catalog.carr.org/view.aspx?ctx=19.1033.0.0.4&cn=9999,24354

To limit to Hoover Library:

https://catalog.carr.org/search/searchresults.aspx?ctx=19.1033.0.0.4&type=Boolean&term=(CN=609+AND+AB=19)&by=KW&sort=RELEVANCE&limit=&query=&page=0

LINK BY TITLE

https://catalog.carr.org/view.aspx?ctx=19.1033.0.0.4&title={url_encoded_title}

https://catalog.carr.org/view.aspx?ctx=19.1033.0.0.4&title=Misery

https://catalog.carr.org/view.aspx?ctx=19.1033.0.0.4&title=Crime+and+Punishment

Limit to Hoover Library:

https://catalog.carr.org/search/searchresults.aspx?ctx=19.1033.0.0.4&type=Boolean&term=((TI="Crime and Punishment")+AND+AB=19)&by=KW&sort=RELEVANCE&limit=&query=&page=0

Note in the above example that the Boolean stop word "and" in the title necessitates enclosing the entire title in quotes and searching it as a phrase - this applies to any search using a stop word.

Link by Series

https://catalog.carr.org/view.aspx?ctx=19.1033.0.0.4&series={url_encoded_series}

https://catalog.carr.org/view.aspx?ctx=19.1033.0.0.4&series=nora+roberts+american+romance+collection+(mcdaniel+college)

Link by Collection

This search can only be done via Boolean, and does not need a location limiter, as collection codes are specific to each library. The default sort (RELEVANCE) can be changed as needed.

Some collections (i.e. eBooks) are quite large, and exceed the 5000 title limit that shows in the PAC, so a direct link to those collections is not very useful. The smaller, more specialized collections, however, can benefit from a direct link.

The advantage to this method of linking is that they run a new search each time the link is clicked, thus the result list is always up-to-date, as opposed to one that is produced by a record set link (below), which is static.

https://catalog.carr.org/search/searchresults.aspx?ctx=19.1033.0.0.4&type=Boolean&term=COL={collection_code}&by=KW&sort=RELEVANCE&limit=&query=&page=0

Call Numbers

Call number searching is Boolean only, and can take two forms:

DD= is a Dewey number search that goes against the 082 Dewey number in the MARC record. The syntax for that search is:

https://catalog.carr.org/search/searchresults.aspx?ctx=19.1033.0.0.4&type=Boolean&term=(DD=818.4*+AND+AB=19)&by=KW&sort=RELEVANCE&limit=&query=&page=0

LOCAL= is the locally assigned call number in the 092 field of the MARC record. It is a more effective search, as it is more consistent. The syntax for that search is:

https://catalog.carr.org/search/searchresults.aspx?ctx=19.1033.0.0.4&type=Boolean&term=(LOCAL=818.4*+AND+AB=19)&by=KW&sort=RELEVANCE&limit=&query=&page=0​

Note the presence of the "*" after the call number - this picks up everything after the last digit specified, so searches can be as precise as you need them to be (i.e. if you only want 616.23* not 616.22* or 616.24*) AB=19 limits to Hoover items only.

Also note that electronic items such as ebooks and streaming videos often do not have call numbers assigned (this is dependent on the quality of the incoming records), so they may or may not show up in a call number search.

Bibliographic Record Set by Control Number

Library Staff Only

https://catalog.carr.org/view.aspx?ctx=19.1033.0.0.4&brs={bibrecordsetid}

{Where bibrecordsetid is the Polaris control number for the bibliographic record set, found in staff view.}:

Example (DVD Record Set)

https://catalog.carr.org/view.aspx?brs=73414&sort=TI

Note that record sets are static (in that new items will not appear) However, they can be affected by deletions, so that a record that is removed from the system will also be unlinked and removed from a record set). Therefore, this linking method (and linking to a record set by name) is probably only useful on a temporary basis, i.e., if you are manually gathering a number of items with differing collections or formats for a course with a specific end date.

Bibliographic Record Set by Name

Library Staff Only

This is functionally the same as the section above by record set number.

https://catalog.carr.org/view.aspx?ctx=19.1033.0.0.4&brsn={'bibrecordsetname'}

Where bibrecordsetname is the name of the record set, and needs to be enclosed in quotes:

https://catalog.carr.org/view.aspx?ctx=19.1033.0.0.4&brsn="HL Faculty Publications-Book River_20120917140259"
