There are a number of ways of locating medieval manuscripts: by library catalog, by online sites (which are often library catalogs), and through listings of incipits.
The Patrologia Latina and Library of Latin Texts can in effect be used as a database of incipits to identify texts, and the edition cited can then be consulted for lists of manuscripts.
A select Listing of Sites
Digital Scriptorium (DS) is a growing organization of institutional partners with collections of medieval and Renaissance manuscripts. DS provides an online union catalog of these collections and thus unites scattered resources from many institutions into an international tool for teaching and scholarly research. As a digital image repository, the DS website allows users to verify with their own eyes descriptive metadata about places and dates of origin, scripts, artists, and decoration.
Friedrich Stegmueller's multi-volume Repertorium Biblicum Medii Aevi
The RBMA contains thousands of Latin religious texts, including commentaries and other theological writings and lists their manuscripts and editions.
The principal objective of Europeana Regia is to reconstruct, in the form of a virtual library, the most important European royal collections of documents from the Middle Ages to the Renaissance. Managed by the Bibliothèque nationale de France (BnF), Europeana Regia unites five European libraries—the Bayerische Staatsbibliothek, Munich (BSB), the Universitat de València Biblioteca Històrica (BHUV), the Herzog August Bibliothek, Wolfenbuttel (HAB), and the Koninklijke Bibliotheek van België-Bibliothèque royale de Belgique (KBR)—and encompasses almost nine hundred manuscripts that are representative of the political, cultural and artistic history of Europe.
The Goodspeed Manuscript Collection
The Edgar J. Goodspeed Manuscript Collection comprises 68 early Greek, Syriac, Ethiopic, Armenian, Arabic, and Latin manuscripts ranging in date from the 5th to the 19th centuries. The acquisition of these hitherto unknown manuscripts was spearheaded by Edgar J. Goodspeed in the first half of the twentieth century in order to support new scholarship in the humanities. The University of Chicago Library is providing a unique digital resource based on this collection. All 68 New Testament manuscripts have been digitized in their entirety and are presented with high-quality zoomable images through an interface that supports browsing within individual manuscripts and across the collection.
The Manuscriptorium project is creating a virtual research environment providing access to all existing digital documents in the sphere of historic book resources (manuscripts, incunabula, early printed books, maps, charters and other types of documents). These historical resources, otherwise scattered in various digital libraries around the world, are now available under a single digital library interface. The service provides seamless access to more than 5 million digital images.
The Monastic Manuscript Project is a database of descriptions of manuscripts that contain texts relevant for the study of early medieval monasticism, especially monastic rules, ascetic treatises, vitae patrum-texts and texts related to monastic reforms. The purpose is to offer a tool for reconstructing not only the manuscript dissemination of early medieval monastic texts but also to give access to the specific contexts in which a text appears. Most pages provide links to a number of web resources, such as manuscript catalogues, online texts and translations, digitized manuscripts and repertoria. Manuscript descriptions are usually based on published manuscript catalogues and secondary literature.
Schoenberg Database of Manuscripts
The Schoenberg Database of Manuscripts aggregates observations of premodern manuscripts drawn from over 12,000 auction and sales catalogues, inventories, catalogues from institutional and private collections, and other sources that document sales and locations of these books from around the world. Using thirty-six possible fields, entries in the Schoenberg Database of Manuscripts (SDBM) record data from observations made in these sources and assist researchers in locating and identifying particular manuscripts, establishing provenance, and aggregating descriptive information about specific classes or types of manuscripts.

Free Library of Philadelphia’s digital collection of medieval and Renaissance manuscripts
The manuscript collection includes most of the kinds of books used between 1000 and 1500 A.D.: prayer books and poetry, Bibles and political propaganda, philosophical works, and fantastic histories. Some manuscripts are elaborate and beautiful works of art; others are humble "owner-produced" books, copied out from a borrowed copy by someone who needed a particular text. Each one tells us something about a long-vanished age.

Bibliotheca Palatina Digital One of the consequences of the Thirty Years War was that the most important collection of books in the 17th century Holy Roman Empire, the Bibliotheca Palatina, was divided between two principal locations: Heidelberg and the Vatican. Since 2001, Heidelberg University Library has been working on several projects that aim to digitize parts of this great collection, the final goal being a complete virtual reconstruction of the “mother of all libraries.”
