566661 Introduction
Online resources are used in a diverse and expanding set of ways in particle physics. Many ofthese resources have become central to our collective work. We provide a brief curated selectionof the major resources here. An expanded and regularly updated online repository is referred tobelow and can be found athttps://github.com/particledatagroup/hep-resources
By contrast, it is meant to be inclusive and catalog all useful resources related to particle
physics. The community is warmly invited to contribute in order to ensure a broad and up to datecoverage of relevant resources. Practical details are available online.

2 Particle Data Group (PDG) resources• Review of Particle Physics (RPP): A comprehensive report on the fields of particle
physics and related areas of cosmology and astrophysics, including both review articles anda compilation/evaluation of data on particle properties. The review section includes articles, tables and plots on a wide variety of theoretical and experimental topics of interest toparticle physicists and astrophysicists. The particle properties section provides tables of published measurements as well as the Particle Data Group’s best values and limits for particle
properties such as masses, widths, lifetimes, and branching fractions, as well as an extensive
summary of searches for hypothetical particles. RPP is published as a large book every twoyears, with partial updates made available once each year on the web.
All the contents of the book version of RPP are available online:
https://pdg.lbl.gov
The printed book can be ordered:https://pdg.lbl.gov/order
Of historical interest is the complete RPP collection which can be found online:
https://pdg.lbl.gov/publications• Particle Physics booklet: An abridged version of the Review of Particle Physics, availableas a pocket-sized 250-page booklet. It is one of the most useful summaries of physics data.

3 Particle physics information platform
INSPIRE: INSPIRE serves as a one-stop information platform for the particle physics community, comprising interlinked databases on literature, authors, jobs, seminars, conferences, institutions and experiments (each described in more detail below). Run in collaboration by CERN
(which hosts INSPIRE), DESY, Fermilab, IHEP, IN2P3 and SLAC, it has been serving the scientific community for almost 50 years. Previously hosted at SLAC and known as SPIRES, it was
the first website outside Europe and the first database on the web. Close interaction with theuser community and with arXiv, ADS, HEPData, ORCID, PDG and publishers is the backboneof INSPIRE’s evolution. Since 2020, it is running on a modernized platform that is continuously
being improved.

4 Literature databases
Most research articles in the field of high-energy physics are first made available on the arXiv
eprint server, where researchers can learn about the latest developments by browsing through thenew announcements five days a week. They are indexed, together with all other publications inhigh-energy physics and related fields, in the INSPIRE literature collection. For neighboring fields
such as astrophysics or mathematics, other databases are more exhaustive.
• ADS: The SAO/NASA Astrophysics Data System is a Digital Library portal offering accessto 15 million bibliographic records in Astronomy and Physics. The ADS search engine also
indexes the full-text for many publications in this collection and tracks citations. The system
also provides access and links to a wealth of external resources, including electronic articles
hosted by publishers and arXiv, data catalogs and a variety of data products hosted by theastronomy archives worldwide. The ADS can be accessed at:

http://ads.harvard.edu/• arXiv.org: A repository of full-text articles in physics, astronomy, mathematics, computerscience, statistics, nonlinear sciences, quantitative finance, quantitative biology, electricalengineering and systems science, and economics. Papers are submitted by registered authors
to arXiv, often as preprints in advance of submission to a journal for publication; includes
postprints, working papers, and other relevant material. Established in 1991, the repository
is interlinked with ADS and INSPIRE, among others. Readers can browse subject categories
or search by author, title, abstract, date, and other fields. Receive daily update alerts for
subfields by email or RSS.

Online Particle Physics Information

11 Software packages and repositories
A vast number of software tools are used for various aspects of high-energy physics research.
Due to their number, their often specialized purpose and the quickly-changing nature of software,no attempt has been made to present them in this chapter. The accompanying online version
contains an extensive categorized list of software.

12 Data repositories and preservation
Initiatives to preserve and disseminate data produced during different stages of research, fromMonte Carlo events to machine-readable versions of tables in papers, have grown in recent years.
Unfortunately, there currently exists no central resource aggregating all these data as is the case forthe more established means of scholarly communication. Instead, there are a number of repositories
targeting different types of data and research subjects. They are listed in the online version.

13 Particle physics education and outreachParticle physics public engagement efforts are widespread, with laboratories, experiments, universities and individual researchers engaged in a range of efforts. The online version of this chapter
provides links to resources for particle physicists wanting to become engaged in public education as
well as resources that physicists can provide directly to students, teachers or lay people. There areclassroom activities, interactive websites, films, and direct links to education offices at institutions
and experiments. Many researchers also engage the public via a variety of social media platforms.
Additionally, a selection of news sites relevant for experts and for the general public are provided.

14 Regional HEP efforts
The online version of this chapter provides links to summaries of regional HEP activities acrossEurope, Japan, the US, Africa, Latin America, and other regions that may be classified as developing or emerging. This list of summaries is not exhaustive and is based on the expert knowledgeof the authors at the time of information gathering; the narrative was developed in July 2023 andwill require periodic updates as the HEP landscape changes.
