Answers to Frequently Asked Questions about ILLiad

What is ILLiad?

ILLiad is the electronic system you use to request an item through Interlibrary Loan. The name ILLiad can be thought of as an acronym for InterLibrary Loan internet accessible database.

What can I request?

Document Delivery provides books, theses and dissertations, CDs, videos, journal articles, microforms, music scores, maps and other research items, both within and outside the Texas Tech University Libraries' collections.

  • Books, videos, CDs, musical scores, maps

    We can locate and pull the items you need (excluding journals and non-circulating items) from stacks and hold them for you. If the requested material is not in our collection, we will supply you with a copy from another library, as a short-term loan. This service is free.

  • Journal articles

    You may request scans of articles in our collection. Journals are generally non-circulating items (both at Texas Tech Libraries and elsewhere), so we cannot provide you with entire journals. You may request separate articles instead.

  • Theses and dissertations

    In most cases, we are able to supply copies of theses/dissertations published at other universities. If, however, the corresponding library cannot lend a thesis/dissertation, we can assist you in purchasing a personal copy for a flat fee of $33.00. Before we place a purchase request, we will contact you for confirmation.

  • Textbooks

    We do not process textbook requests. Consortial agreements between libraries prohibit the exchange of textbooks. Therefore, requests for textbooks not in our collection will be cancelled.

  • Rare items

    While we can attempt to request rare items (e.g., old books, artifacts) for your research, please be advised that such items are generally non-circulating and the corresponding library/institution may refuse a loan. Instead, you could use the article request form to obtain scans.

How long does it take for requested materials to arrive?

Items owned by Texas Tech University Libraries are usually ready in 24 hours. However, during times of peak library use, extra time may be needed to fill a request. If this library does not own an item, it will be requested from another institution/library. Materials borrowed from other libraries and institutions usually take 4 to 6 days to be delivered. Articles are usually delivered within 48 hours. Items ordered from outside the region are likely to take longer.

How will I know when the materials are available?

We will email you as soon as your items are ready for delivery or pick up. Multiple requests are not always ready for pick up or delivery at the same time. Scanned articles will be delivered electronically to your ILLiad account. You can check the status of an item by logging into your ILLiad account.

How long can I have a book and can I renew it?

Renewals are determined by the lenders and they will generally grant you an additional two to four weeks to your loaned item. You will be able to renew your item 10 to 3 days before the due date by logging into your ILLiad account, clicking on "Checked Out Items/Renewed Items," selecting the specific item that needs to be renewed and then clicking on "Renew Request."

Failure to honor due dates, lending restrictions and recalls could result in the loss of borrowing privileges.

Checkout policies for items from our collection vary according to material type and patron status. Items supplied from other institutions are generally due 3 to 5 weeks after arrival. A notice will be sent to you 10 to 3 days before the due date of your item. Failure to return ILL items will result in a penalty fee of $225 per item charged to your account at Texas Tech University Student Business services and a block will be put on your account.

What if I am a Distance student?

If you are a distance-learning student, please select that status and give us your street address. This will enable us to ship items to you via Fed Ex.

Who may use the service?

Document Delivery services are available to current TTU faculty, students and staff. Users from other institutions/libraries need to contact their "home" library or institution for this service. Specifically, Law School and Health Sciences Center faculty, students and staff need to avail themselves of their own libraries' services. Lubbock area residents should submit their requests at the Lubbock Public Library.

Where can I pick up my materials?

Document Delivery materials are distributed at the Document Delivery Office of the University Library. Materials requested by faculty are delivered Monday through Friday during the fall and spring semesters and Monday, Wednesday and Friday during the summer sessions. Items for off-campus faculty (such as faculty at the Reese Center) are delivered via the Campus Mail Stop facility.

Scanned articles are yours to keep. Borrowed items must be returned to the Document Delivery Office or Circulation desk by the due date. Please do not remove any affixed straps or documentation from the items on loan.

Pick-up service is available for on-campus faculty. To have library items picked up from your department and returned, please contact Circulation at 742.2265 or email to

Is there a limit to the number of requests I can make?

No. Request all you need for your research. But high volumes take longer to fill, so please keep that in mind.

Why don't I see all my older requests when I look at my request history?

From time to time we purge older records from ILLiad. Our policy is to keep requests online for several years order to comply with record keeping requirements of the Copyright Law.

What is electronic delivery?

Many libraries ship photocopies of articles to us in electronic format. In the past, we printed these articles before delivering them to you. Now, through ILLiad, we are able to offer you the option of electronic delivery of these articles in PDF format (Adobe's Portable Document Format). You can read more about electronic delivery on the Electronic Delivery Information page.

Can I have an ILL book the whole semester?

No — unless the lending library’s due date is at the end of the semester. But you can request the same book about a week or so before the book you currently have is due. That way, you won’t be without that book for long, if at all.
