The 5th edition of the Roma-BZCAT Multifrequency Catalogue of Blazars is available in a printed version and online at the ASDC website (http://www.asdc.asi.it/bzcat); it is also in the NED database. It presents several relevant changes with respect to the past editions which are briefly described in this paper.

High-energy sources at low radio frequency: the Murchison Widefield Array view of Fermi blazars
This is the accepted version of the following article: Giroletti, M. et al., A&A, 588 (2016) A141, which has been published in final form at DOI: http://dx.doi.org/10.1051/0004-6361/201527817. This
Optical Variability of a Newly Discovered Blazar Sample from the BZCAT Catalog
In an optical monitoring program to characterize the variability properties of blazars, we observed 10 sources from the Roma-BZCAT catalog for 26 nights in V and R bands during 2014 October to 2015
Blazars in the LOFAR Two-Metre Sky Survey first data release
Historically, the blazar population has been poorly understood at low frequencies because survey sensitivity and angular resolution limitations have made it difficult to identify megahertz
Activity Types of Galaxies Selected from an HRC/BHRC Sample. II
This is a detailed spectral classification of 198 candidate active galactic nuclei (AGN) from a joint HRC/BHRC sample consisting of a combination of the HRC (Hamburg-ROSAT) and BHRC (Byurakan-ROSAT)
Identifying the 3FHL Catalog. I. Archival Swift Observations and Source Classification
We present the results of an identification campaign of unassociated sources from the Fermi Large Area Telescope 3FHL catalog. Out of 200 unidentified sources, we selected 110 sources for which
An Optical Overview of Blazars with LAMOST. II. Gamma-Ray Blazar Candidates and Updated Classifications
Blazars represent the dominant class of associated γ-ray sources detected by the Fermi Large Area Telescope (LAT). However, in the more recent release of the Fourth Fermi-LAT Point Source Catalog
The Fourth Catalog of Active Galactic Nuclei Detected by the Fermi Large Area Telescope
An incremental version (4LAC-DR2) of the fourth catalog of active galactic nuclei (AGNs) detected by the Fermi-LAT is presented. This version is associated with the second release of the 4FGL general
Planck intermediate results
This paper presents the Planck Multi-frequency Catalogue of Non-thermal (i.e. synchrotron-dominated) Sources (PCNT) observed between 30 and 857 GHz by the ESA Planck mission. This catalogue was
3FHL: The Third Catalog of Hard Fermi-LAT Sources
We present a catalog of sources detected above 10 GeV by the Fermi Large Area Telescope (LAT) in the first 7 years of data using the Pass 8 event-level analysis. This is the Third Catalog of Hard
Simultaneous spectra and radio properties of BL Lacs
We present the results of 9 years of the blazar observing program at the RATAN-600 radio telescope (2005–2015). The data were obtained at six frequency bands (1.1, 2.3, 4.8, 7.7, 11.2, and 21.7 GHz)

Roma-BZCAT: A multifrequency catalogue of Blazars
We present a new catalogue of blazars based on multi-frequency surveys and on an extensive review of the literature. Blazars are classified as BL Lacertae objects, as flat spectrum radio quas ars or

Blazars constitute the most enigmatic class of extragalactic γ-ray sources, and their observational features have been ascribed to a relativistic jet closely aligned to the line of sight. They are
