- Catalogue of Variable Stars in Globular Clusters - A catalogue of variable stars in globular clusters, featuring, for each cluster, single variables listed with pulsational parameters (period).
- A Galactic Globular Clusters Database - Searchable database of galactic globular clusters parameters. Clusters have colour-magnitude diagrams and Digital Sky Survey images.
- Globular Cluster Omega Centauri - Does an old, red globular cluster have any hot, blue stars? Photos taken in two wavelength bands, with comments on stellar evolution in the cluster.
- Globular Star Clusters - Information from SEDS on globular clusters.
- Databases of Padova Astronomy Department - 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".
- Globular cluster M15 - A large image and a discussion of M15 as a candidate for an example of core collapse.
- Globular Clusters in the Andromeda Galaxy - Data, observation notes, and more about globular clusters within the galaxy.
- List of Common Deep Sky Catalogs - General, supernova remnants, planetary nebulae, diffuse nebulae, dark nebulae, open clusters, globular clusters, galaxies, clusters of galaxies, double stars, and references.
- The National Deep Sky Observers Society - Contains information, challenges, galaxy clusters, globular clusters, open star clusters, naked eye observations, observing planetary nebulae, the Milky Way, and star hopping.

- Globular cluster - A globular cluster is a spherical collection of stars that orbits a galactic core as a satellite. Globular clusters are very tightly bound by gravity, which gives them their spherical shapes and relatively high stellar densities toward their centers.
- Stellar association - A stellar association, or moving group, is a very loose star cluster, looser than both open clusters and globular clusters. Stellar associations will normally contain from 10 to 100
- Shapley–Sawyer Concentration Class - The Shapley–Sawyer Concentration Class is a classification system on a scale of one to twelve using Roman numerals for globular clusters according to their concentration. The most highly concentrated clusters such as M75 are classified as Class I, with successively diminishing concentrations ranging to Class XII, such as Palomar 12.
- Open cluster - An open cluster is a group of up to a few thousand stars that were formed from the same giant molecular cloud, and are still loosely gravitationally bound to each other. In contrast, globular clusters are very tightly bound by gravity.
