Translation Services
Machine translation services (where a computer does the translating) produce very crude translations that give you the gist of a document, but are not reliable (or quotable). Google translate is often the best. See below a list of other options. Professional human translators are expensive.

Automatic machine translation services
If you plan to scan an article in a paper journal and then use automatic machine translation, keep the following in mind. Your OCR (scanning) software should have a dictionary for the language you are scanning (e.g., German). If it does not, it will make many, many spelling errors and no machine translation service will give good results. If you plan to manually key in the text, read the online help at that translation site about how to enter accents, umlauts and other special characters first.
Try Google translate first. It uses statistical methods to translate between more than 50 languages, including French, German, Greek and Hebrew. The software learns to translate by comparing original texts and translations prepared by humans. Google translate works well when it has a few hundred billion words of text of analyze, as is the case with common European languages, but it works poorly when it has much less text to learn from. So the results in some languages is quite bad. You can upload text or give it the url of a document to translate.

Human translation services
This is often the only way to get a reliable translation, but be prepared to pay $.30 per word or more if you use a professional. Perhaps you can use free automatic machine translation to get the gist of an article, identify the key pages and passages, and then ask a human translator to produce a polished translation of the key passages. Let the library know if you discover translators are willing to accept small jobs like that.

Indexes of Published Translations
Index translationum: International Bibliography of Translations lists translations of books published by member states of UNESCO. It does not include journal articles. The paper edition (which is in some DFW area libraries) covers from 1932 to date. The database begins coverage with 1979. You can search by author, title, publisher, translator, etc.
WorldCat is another excellent source of finding books translated into English. You can search by author or title.
On rare occasion you will find a translation of a journal article cited in ATLA.
There are several US agencies that regularly translate foreign newspapers and journals. They do a good job with public affairs (political, economic, social, cultural) publications and with STM (scientific, technical and medical) literature, but make almost zero effort to cover humanities or religion in particular (unless it relates to terrorism!). There is very little chance any of these agencies has translated the theological article you are interested in, but check the Open Source Center and BBC Worldwide Monitoring.
