# Overview of Problem Libraries

## Open Problem Library (OPL)

The Open Problem Library contains problems from several of the File-Based Problem Libraries, including all of the problems from the Arizona State, Rochester, California State-Long Beach, University of Virginia, and the Utah libraries. It also contains most, if not all, of the problems from Union College, The College of New Jersey, Dartmouth, Ohio State, Northern Arizona University, and Indiana University.

In addition to merging these problem collections into a single collection, WeBWorK provides a different interface to these problems. Problems in the OPL are marked internally with metadata, so instructors can search for problems on the basis of this data. This mechanism is built into WeBWorK's library browser. In particular, one can search hierarchically by course, chapter, or section. To a limited extent, problems have been indexed against textbook sections; therefore, instructors can also search for problems on that basis. WeBWorK stores this information in a database, so part of the installation involves loading metadata into the database.

**For more information on downloading, installing, browsing and contributing to the OPL, See: Open Problem Library**

## File Based Problem Libraries

These libraries consist of a directory tree organized roughly by the chapters of a canonical calculus book (or in some cases a canonical text for another subject). There is no database index of tagged metadata. One should regard the material in these libraries as legacy material since we are in the process of adding metadata (tagging the problem), checking the problems for errors and duplicates, and folding them into the OPL.

- The "(CVS)" links for each library allow you to inspect the contents of the library over the web.
- See CVS Access to Problem Libraries for instructions on downloading the contents of these libraries via CVS.
- You can find tarballs of each libraries at http://webhost.math.rochester.edu/webworkdocs/librarytarballs.

### Arizona State University Math Problem Library

This problem library is now empty. All of the problems have been moved into the Open Problem Library.

### The College of New Jersey Math Problem Library

The College of New Jersey (TCNJ) makes a large number of linear algebra
problems available in this collection. Please send links of any problems that do not
work to Tom Hagedorn, `hagedorn at tcnj.edu`

.

(CVS)

**To check out this library:**

cvs -d :pserver:anoncvs@cvs.webwork.rochester.edu:/webwork/cvs/tcnj co tcnj_problib

### Dartmouth College Library

This library has problems compatible with the Marsden and Tromba multi-dimensional calculus book. It also has problems compatible with the later chapters in Stewart's calculus book. (CVS)

**To check out this library:**

cvs -d :pserver:anoncvs@cvs.webwork.rochester.edu:/webwork/cvs/dartmouth co dartmouth_problib

### Detroit County Day School Math Problem Library (High School)

These high school and pre-calculus level problems were written by Mark Schmidt at Detroit Country Day School. Send corrections to `gage at math.rochester.edu`

or to `M.Schmitt at dcds.edu`

. (CVS)

**To check out this library:**

cvs -d :pserver:anoncvs@cvs.webwork.rochester.edu:/webwork/cvs/dcds co dcds_problib

### Indiana University Math Problem Library

No description. (CVS)

**To check out this library:**

cvs -d :pserver:anoncvs@cvs.webwork.rochester.edu:/webwork/cvs/indiana co indiana_problib

### Northern Arizona University Library

The Northern Arizona University Library has new problems for graph theory, statistics and pre-calculus. The `setExamples`

set cleans up some of the problems
in the Rochester Library's `setMAAtutorial`

set and adds several more.
Send corrections to `Nandor.Sieben at nau.edu`

. (CVS)

**To check out this library:**

cvs -d :pserver:anoncvs@cvs.webwork.rochester.edu:/webwork/cvs/nau co nau_problib

### Union College Math Problem Library

The Union College Math Problem Library should now be fully functional. A few of the problems may not work as advertised, since they may have trouble finding the links to auxiliary materials, such as external graphs.

Davide Cervone and Kathryn Leash are principally responsible for designing these problems. The level set and 3d problems are particularly nice!!

Please send links of any problems that don't work to `gage at math.rochester.edu`

or `dpvc at union.edu`

or, better yet, enter them into the WeBWorK bugzilla via the "report problem bugs" on the PG editor page. (CVS)

**To check out this library:**

cvs -d :pserver:anoncvs@cvs.webwork.rochester.edu:/webwork/cvs/union co union_problib

### UC Santa Barbara and Brooks/Cole

Problems inspired by Stewart's Calculus book. (CVS)

**To check out this library:**

cvs -d :pserver:anoncvs@cvs.webwork.rochester.edu:/webwork/cvs/ucsb co ucsb_problib

### University of Georgia Math Problem Library

WeBWorK mathematics homework problems created at the University of Georgia. Send corrections to Ted Ashton (ashted at math.uga.edu) or, even better, enter them into bugzilla via the "report problem bugs" on the PG editor page. (CVS)

**To check out this library:**

cvs -d :pserver:anoncvs@cvs.webwork.rochester.edu:/webwork/cvs/uga co uga_problib

### University of Michigan Math Problem Library

This library contains problems related to the Hughes-Hallet et.al. Harvard Calculus text. Send corrections to Gavin LaRose, `glarose at umich.edu`

, or even better, enter them into the WeBWorK bugzilla via the "report problem bugs" on the PG editor page. (CVS)

Note, however, that in the file-based library, there are also files for the University of Michigan Gateway Tests, which are not currently incorporated into the OPL.

**To check out this library:**

cvs -d :pserver:anoncvs@cvs.webwork.rochester.edu:/webwork/cvs/umich co umich_problib

### University of Rochester Math Problem Library

The Rochester Math Problem Library should now be fully functional. A few of the problems may not work as advertised, since they may have trouble finding the links to auxiliary materials, such as external graphs. Please send links of any problems that don't work to `gage at math.rochester.edu`

or even better enter them into the WeBWorK bugzilla via the "report problem bugs" on the PG editor page. (CVS)

The Rochester library includes many problems prepared by Zbigniew Fiedorowicz at Ohio State University as well as a large number of problems prepared by Jun Wang at Alabama State University

**To check out this library:**

cvs -d :pserver:anoncvs@cvs.webwork.rochester.edu:/webwork/cvs/rochester co rochester_problib

### University of Rochester Physics Problem Library

These physics problems were originally written in CAPA and mechanically translated into the PG language. Thanks to help from Frank Wolfs, the .eps file pictures now display properly. (CVS)

**To check out this library:**

cvs -d :pserver:anoncvs@cvs.webwork.rochester.edu:/webwork/cvs/rochester co rochester_physics_problib

### University of Rochester Grade 8 Math Problems

These problems, written largly by Tori Sweetser, contain material at the level of
the New York State 8th grade exams. Many of these problems are written using the multiple choice and matching tools. Send corrections to `gage at math.rochester.edu`

. (CVS)
