Can I have all of my library's holdings removed from the Locator and resubmit them?
The Locator union catalog is a very large database with over 4 million bibliographic records and 16 million item records. Deleting records from such a large database can be a complex and time consuming task. In most cases SILO will not allow a library to delete all of their holdings from the Locator.
Instead, libraries should resubmit all of their holdings. Records that have standard numbers will overlay with existing records when they're loaded. The standard numbers used in the match include ISBN, ISSN, LCCN, and OCLC number. When an item is requested through SILO ILL that a library no longer owns, mark the request "Do not own", and use the online delete feature in SILO ILL to remove the item from the Locator.
SILO may allow a library to remove all of its holdings from the Locator, if the library has made major changes to its catalog. Please contact the Des Moines office for more information.
How can I check the status of a loan request?
You can check the status of a loan request by viewing the contents of the SILO ILL queues or by viewing the history of a specific ILL transaction.
There are four unique queues in the SILO ILL system:
- Borrower Open
- Borrower Closed
- Lender Open
- Lender Closed
When you make a loan request it stays in the Borrower Open queue until it's filled or it's completed it's run through the system. After the request is filled or completed, it moves to the Borrower Closed queue. To check the status of a recent loan request, view the Borrower Open queue first. If the loan doesn't show up there, view the Borrower Closed queue.
For instructions on viewing the Borrower Open queue, please see section 10.40.10 of the SILO ILL users manual. To view the Borrow Closed queue, follow the same instruction, but at step #3 select "Borrower" and "Closed" from the drop-down menus instead.
If you know the specific ILL transaction number, you won't need to search through the queues. You can go directly to the transaction history instead. For instructions on viewing the history of an ILL transaction, please see section 10.60.00 of the SILO ILL users manual.
How do I submit my library's holdings to the Locator?
If your library is a participating library in the SILO Interlibrary Loan System, you have a couple of options for adding the bibliographic records of materials owned by your library to the SILO Locator:
- submit records one at a time using online add
- submit batches of MARC records using MARC file upload
Libraries that catalog through OCLC may have their records included in monthly transaction tapes which contain new records as well as notifications of delete records.
I submitted my holdings a few days ago. Why aren't they showing up in the Locator?
Records that are submitted through the online add/delete feature or MARC file upload should be available in the Locator by 9:00 AM the next business day. This schedule is subject to staff availability, and may occasionally be delayed by a day or two.
Records that do not met the minimal MARC guidelines will take not be loaded. Invalid MARC records and records in other formats will not be accepted.
System maintenance may delay both of these schedules by a few days or weeks. Delays will be announced on the SILO ILL mailing list.
What should I do when I receive the error message: "Invalid or expired session"
This can occur when a transaction that requires confirmation gets stopped before it has fully completed. Examples of these kinds of transactions include: submitting a new loan request, processing a pending request, and uploading MARC files. To prevent the error from occurring in these situations, avoid using the back button in your browser or clicking on hyperlinks while web pages are loading.
This error can also occur when your login session was initiated over a month ago. To prevent the error from occurring in this situation, do not bookmark pages inside the SILO ILL System. You should bookmark the web page at the following URL, and login with your Locator code and password each time you use the system:
Why do I receive two or more copies of the same item?
This usually occurs when a transaction has expired in the queue, and the request has moved onto the next lender. The item is sent by the first lender without a response to the SILO ILL system, so the next lender in the queue also sends the item.
Lending libraries should respond to requests within four working days (Monday-Friday). Items should not be sent without first processing the transaction on the “Lender Open” page of SILO ILL.
If you receive more than one copy of an item, please report the problem to your District Office. One of the lending libraries may need additional training on the SILO ILL system.
