Searchable database of galactic globular clusters parameters. Clusters have colour-magnitude diagrams and Digital Sky Survey images.

This catalog contains basic parameters on distances, velocities, metallicities, luminosities, colors, and dynamical parameters for 147 objects regarded as globular clusters in the Milky Way galaxy. Compiled by William E. Harris, McMaster University.

A catalogue of variable stars in globular clusters, featuring, for each cluster, single variables listed with pulsational parameters (period).

Databases maintained by the Padova Astronomy Department (Italy) with a lot of info for each galactic cluster. Three different databases are available: "Ground-based Data", "HST Snapshot" and "HST Deep".

Information from SEDS on globular clusters.

Introductory information on globular clusters, a diagram of their distribution in the galaxy, information about their research.
