Hotlinks, statement of problemMemo sent to OCLC Navigator team, August 5, 2008You have asked us to describe our concern about hotlinks -- connections to electronic resources. After describing it (A-E) I've listed two questions. --Nancy ______________________________________________________________________________ In a nutshell, wherever the hotlink is stored in the local database, and however it's displayed in the local catalog, it must be picked up and interpreted appropriately for the WorldCat Group Catalog so that all those patrons who should have access will get access (and those who shouldn't won't get access). A. Our members store hotlinks in MARC tag 856 fields in bibliographic and holdings records (III items and checkins). A few also store URLs that are not "hot" (don't link) in Notes fields such as MARC tag 530 and 538. Hotlinks can be in bibliographic, item, and checkin records, and there can be more than one hotlink in a record. In the 856, members use a variety of subfields. I can provide details if necessary. http://www.orbiscascade.org/index/wg-catalog-hotlinks-survey-results B. Members use a variety of plain language text to provide instruction for their patrons who may be students or community users, and C. Some resources are free, but most are proprietary, i.e. purchased by subscription and available only to authorized users. Not every catalog user will be allowed to use every hotlink that displays in the catalog. Any number of patrons -- students, staff, faculty, community patrons, people surfing the web etc. -- may use a library catalog. While all catalog users might be authorized to use the "free" online resources displayed in that catalog, only some of those users would be authorized to use proprietary resources, and for a specific user (or user group), perhaps authorized only for specific resources, not all resources. Sometimes the OCLC record has a proprietary link that will work for none of the Alliance libraries (example, #74809590). so: D. The link in an Alliance library's record is often specific to the library, not "generic." E. Relationship to batchloading/reclamation phase: (1) As one member describes, "Most of our links are stored in ERM checkins [checkin records] that are attached to Serials Solutions MARC records. WorldCat does not contain all the titles that Serials Solutions offer. I have already noticed that some of our e-holdings are not attached to WorldCat due to various reasons, such as mismatches, lack of ISSNs in OCLC, and etc." (2) Many members use "single record" cataloging, that is, attaching hotlinks and holdings information for electronic and print and/or microform versions to the same record. As members send records to OCLC, holdings may be attached to only one of two appropriate records, Tracy DeGood is aware of the situation. ***1. Please describe for us how Navigator and "screen scraping" will provide the appropriate working hotlinks according to the member's unique situation, i.e. not the same as every other member in Summit, and not the same as every library in WorldCat. ***2. Please advise on how OCLC will handle and represent holdings for all versions of a title - print, electronic and/or microform etc. ________________________________________________________________ For some interesting examples in Summit, see these three titles: .
