Library Card & Catalog Questions

What is my library card number and how should I enter it?
Your library card number is below the barcode on the back of your Denver Public Library card. It always starts with the letter D, followed by the number 0 (zero), followed by eight additional numbers. In the example below, you would enter D010101010. Enter the number without spaces.

If your card number is still not accepted, contact Circulation or call your library to confirm the card number and spelling of your name.

Why do I get an error message when I try to connect to the library catalog?
The catalog is located at http://catalog.denverlibrary.org

Sometimes the catalog goes down. If we know about it in advance, we put a notice on our site, but that's not always possible. If you tried to connect while the system was down, the failed connection may remain in your cache or temporary Internet files. Clear your cache or temporary Internet files and try again.

Web Accelerators (used with some dial-up connections) can affect your ability to connect to some library resources. Turn off the accelerator and try again.

You may be using security settings or a firewall that is preventing you from connecting. Your Internet service provider, firewall vendor or network technician can help you adjust the settings.

Why can't I connect to My Library Card?
My Library Card is located at http://mycard.denverlibrary.org/

Sometimes access to My Library Card goes down. If we know about it in advance, we put a notice on our site, but that's not always possible. If you tried to connect while the system was down, the failed connection may remain in your cache or temporary Internet files. Clear your cache or temporary Internet files and try again.

If you entered your library card number incorrectly, the failed connection may remain in your cache or temporary Internet files. Clear your cache or temporary Internet files and try again. See What's my Library Card number and how should I enter it?

If you have not used your library card to check out materials recently, the card may have expired or you may be using an obsolete number. Call the Circulation Desk at 720-865-1332 to check on the status of your card.

Why can't I place a hold?
If your library card is not accepted, see Why can't I connect to My Library Card?

If you cannot place a hold because the locations page cannot be located, first try clearing your cache or temporary Internet files. Exit the catalog, re-open it, and try again. If the problem continues, notify webmaster@denverlibrary.org. There may be a problem with the server that can usually be restored overnight.

I have a very slow connection. Are there any shortcuts I can use?
A low-graphics version of the catalog is available at http://textcat.denverlibrary.org. This version does not contain images of bookjackets or links to supplemental content like reviews.

Be aware that downloading eBooks will take a long time with a slow connection, so plan accordingly. Audio eBooks should be downloaded 1 or 2 parts at a time. eFlicks are very large files and are not recommended for use with dial-up Internet connections.

I need to renew my items and I can't do it online right now. What are my alternatives?
Phone Circulation is an automated, 24-hour telephone service where you can monitor the status of your account and renew your charged materials. Call 720-865-1133. Or you may call the Central Library Circulation desk at 720-865-1325 or your branch library during regular operating hours.

Access from Home or Work

I can't get to my favorite database using Research Resources. What now?
Use this basic A-Z list of databases to link directly to one database.

Why do I get an error message when I try to access a library resource from home or work?
You must use the links on Denver Public Library's Research Resources pages to access resources licensed to the Denver Public Library. The authentication/validation process is built into those links. You can bookmark the most convenient Research Resources page, but a bookmark to the resource itself will not work.

Some resources are not available to remote users. Those marked with the symbol Available in any Denver Public Library can only be used from inside the Library.

If you entered your library card number incorrectly, the failed connection may remain in your cache or temporary Internet files. Clear your cache or temporary Internet files and try again.

If you have not used your library card to check out materials recently, the card may have expired or you may be using an obsolete number. Call the Central Circulation Desk at 720-865-1325 during library hours to check on the status of your card.

Some resources require that the date and time settings on your computer are accurate.

In order to connect to some library resources, cookies must be allowed.

Some databases are not compatible with the AOL browser. After connecting to the Internet, minimize AOL and open Internet Explorer, Firefox or Netscape. See our list of recommended browsers.

You may be using security settings or a firewall that is preventing you from connecting. Your Internet service provider, firewall vendor or network technician can help you adjust the settings.

Port 2048 must be open to allow library card authentication for library resources. Some networks, including some workplaces, have not allowed access to Port 2048. If you cannot log into a library resource or if the connection times out before your library card number is accepted, ask your system administrator to open port 2048.

How do I reserve a computer? Why do I have to reserve a computer?
See Equal Access at DPL.

Does the Library filter the Internet?
The Denver Public Library values free and equal access to information, even when that information may be controversial, unorthodox or unacceptable to others. With its implementation of filtering software, the Denver Public Library continues to uphold its commitments to carefully selected children’s materials and to customers' First Amendment rights while complying with the spirit of the new laws. See Internet Filtering FAQ.

Does the library offer Wireless or Wi-fi?
Wireless access is offered on a limited basis in the Central Library. See Wireless Access at DPL.

eBooks and Audio eBooks

What's the difference between downloadable eBooks/Audio eBooks and NetLibrary?
The Library has two different eBook collections from two different vendors. eBooks, Audio eBooks and eFlicks from Overdrive are downloadable to your home PC and can be transferred to your PDA or personal digital player. NetLibrary eBooks can be read online from the library or from home. See a more detailed comparison.

Why can't I log into my eBook Account?

What software do I need to download eBooks, Audio eBooks or eFlicks?
You will need free software to use eBooks, Audio eBooks or eFlicks. See the Quick Start Guide to get started.

Why can't I download my eBook, Audio ebook or eFlick?

Can Audio eBooks and eFlicks be downloaded to my Macintosh or iPod?
No. Audio eBooks and eFlicks from Overdrive require Windows Media Player 9.0 or higher with Digital Rights Management. Digital Rights Management is technology required by authors and publishers to digitally protect files from unlawful redistribution. Macintosh and iPod do not currently support Windows Media Player with Digital Rights Management. See a current list of supported portable devices.

See eMedia Help.
