Expert Indexing Across Every Discipline
Reduce corrections, protect schedules, and deliver consistent indexing
Integra’s Indexing Services help publishing teams deliver acceptance-ready indexes with predictable timelines, consistent quality, and reduced coordination across titles and editions.
Let's TalkReliable Indexing Across Disciplines
Indexing is no longer a simple end-of-production task. It now runs on tight schedules, across print and digital formats, and within increasingly complex subject areas. Operations leaders are expected to deliver indexes that meet house style, support discoverability, and hold up in technical STEM and nuanced HSS, often with minimal time for revisions. For high-volume lists, indexing is also a coordination risk. Production, editorial, authors, and external indexers must align on scope, style, timing, and edition changes. Small breakdowns, unclear instructions, uneven quality checks, late-stage pagination shifts, or inconsistent freelancer performance, quickly turn into business impact: added review cycles, delayed release dates, higher vendor costs, and inconsistent reader experience across titles.
Key Challenge
Fragmented Vendor Management: Multiple freelancers and suppliers make it difficult to apply consistent standards, track performance, and intervene early.
Inconsistent Quality Control: Ad hoc or late-stage checks allow errors through, triggering repeated correction rounds at the most expensive point in production.
Complex Edition Updates: New editions and content shifts break page references and index structure, creating avoidable rework across titles and seasons.
Unpredictable Turnaround: Variable availability and throughput from indexers introduces schedule risk and last-minute pressure on production teams.
Our Indexing Capabilities
Subject-Smart Indexing
We match each title to indexers with the right STEM, HSS, or professional domain background. Our team applies discipline-accurate terminology and reader-friendly structure to help reduce corrections and speed up editorial approval.
Index Types Coverage
We produce subject, author, combined, and other index types to your specifications. We align on style and depth upfront to keep output consistent across your list to help cut review time and avoid rework.
Edition Update Support
We update indexes using previous and current typeset files and a structured comparison process. Our team reconciles pagination and content changes to protect accuracy to avoid late surprises that push deadlines.
Author Indexing
We build author indexes aligned to your style and naming conventions. Our team checks for consistency, cross-references, and duplication to reduce editorial clean-up, prevent inconsistencies, and speed up approvals.
Combined Indexing
We deliver combined indexes when your program requires multiple access paths in one index. We align upfront on structure and depth, then apply consistent rules across chapters to reduce review friction.
Application Indexing
We index application-focused content where readers need fast navigation by tool, task, or concept. We follow the same structured build-and-edit process to maintain clarity and usability while reducing back-and-forth caused by unclear entry structure.
Custom Index Types
We produce other index types based on author or publisher requirements. We validate scope and apply publisher-specific instructions to help your team gain predictability and avoid last-minute changes that delay release timelines.
Onshore Indexing Management
We manage onshore indexing (US/UK) through a long-standing network of indexers. We select, test, onboard, and coordinate onshore indexers so your team gets reliable coverage without vendor sprawl.
Offshore Indexing Delivery
We deliver offshore indexing with dedicated management, experienced in-house staff, and specialist freelancers. This helps you scale volume while maintaining right-first-time quality—96% of titles accepted without major corrections.

FAQ
Q1: What types of indexes does Integra provide?
We provide subject indexes, author indexes, and combined indexes, plus other index types based on publisher requirements. This lets production teams standardize output across different series and disciplines without reworking structure late in the schedule.
Q2: Does Integra handle STEM and humanities indexing?
Yes. We index across STEM, HSS, and professional domains, supported by indexers with academic backgrounds in sciences, arts, engineering, computers, and humanities. We allocate work based on subject fit to reduce terminology errors and rework.
Q3: How do you select and vet freelance indexers?
We source experienced indexers through indexing societies and referrals, then test them on a sample evaluated by a managing editor. Indexers who pass and sign an NDA are added to the freelancer database. This reduces vendor risk and quality variability.
Q4: How do you ensure indexing quality before delivery?
A managing editor reviews a sample chapter and provides feedback, and we track quality scores over time. We also run QA checks (including checks for blank page numbers and pages exceeding book extent) and use trend analysis to prevent recurring errors. This reduces back-and-forth and supports predictable sign-off.
Q5: How do you manage indexing across large publishing programs?
We plan and allocate work based on indexer skill, subject expertise, availability, and schedule, then monitor quality through structured review and scoring. We also manage freelancer performance through iLancer, our freelancer management system, where project leads rate indexers after each project. This supports consistent outcomes across multiple titles.
Q6: What results have you delivered at scale for indexing?
We processed 748+ titles in 2024–25, with 96% right-first-time acceptance for offshore titles (accepted without major corrections). These outcomes reflect structured workflows and quality governance designed to reduce rework and schedule risk.
